Effect of abbreviated training. The initial training was interrupted after 5 min, and animals were tested either after 0.5 hr (n = 6) or after 24 hours (n = 10). The test was continued until animals stopped responding to the food. Means and s.e.s are shown. (A) The time to stop responding in the test 0.5 hr and 24 hr after training. The time to stop responding after 0.5 hr was similar to that in naive animals, whereas the time to stop responding after 24 hr was similar to that in animals that had been trained with a full training session (see Fig. 1). (B) The time that food was in the mouth during the first 5 min of training and during the first 5 min of the two tests. There were no savings after 0.5 hr, but there were significant savings after 24 hr.
